Methods for Attenuation of Unmanned Aerial Vehicle Noise

Mostafa Mahmoodi; Ali Moradi

Volume 6, Issue 2 , September 2022, , Pages 71-83

  Unmanned aerial vehicles (UAVs) like drones (quadcopters, hexacopters, octocopters, etc.) can be a source of significant acoustic noise. High noise makes them less suitable for use in densely populated urban areas, particularly during take-off, landing, and low-level flight, due to the noise annoyance. ...  Read More

Introducing Methods of Thrust Vector Control (TVC) System in Supersonic Aircraft

Mostafa Mahmoodi; Mohsen Shadravan; Mahmood Kashani

Volume 2, Issue 4 , August 2019, , Pages 17-26

  The methods of aircraft controlling such as missiles and airplanes have been based on the displacement of aerodynamic plates along the air flow path. A new method that has been studied seriously in recent years is a change in the direction of the output flow vector of the aircraft engine. Depending on ...  Read More
